Cholesterol Levels May Spike During Winter Months

Tendency to eat more, exercise less when it's cold and snowy outside may explain trend

continued...

Dr. Suzanne Steinbaum, a preventive cardiologist at Lenox Hill Hospital in New York City, added that people should not shrug off the potential health effects of these seasonal fluctuations in their blood cholesterol.

Even though people's cholesterol will decrease during the summer, the high winter levels will contribute to hardening and blockage of the arteries, and increase their risk of heart disease and stroke, she said.

"There's so much research out there about the effects that a high-fat diet can have on the lining of the arteries, even in a one-meal setting," Steinbaum said. "It's very easy to make excuses in the winter, for all of us, but we have to fight it. We have to pay more attention to what we're eating and we need to get our exercise in."

And, added Dr. Evelina Grayver, director of the Coronary Care Unit at North Shore University Hospital in Manhasset, N.Y., the cholesterol fluctuations also could point to other seasonal health effects.

"If we were to look at other cardiovascular risk factors like blood pressure and blood glucose, we likely would have the same findings as well," Grayver said.

Joshi said that even if unhealthy winter habits have nothing to do with the rise in cholesterol levels, people will still benefit if they maintain year-round the exercise and healthy eating that comes so easily in the summer.

"At least the healthier habits will protect you from the cholesterol changes that are happening in the winter," Joshi said.

However, he does not think that the levels fluctuate wildly enough that doctors should check cholesterol only at set times of the year, or test cholesterol repeatedly during the year.

"I don't think there's anything here to say we should change practice from a clinical level," he said.

The data and conclusions of research presented at medical meetings should be viewed as preliminary until published in a peer-reviewed journal.

Congratulations! Your total cholesterol level is in the Desirable range, and your level of "bad" LDL cholesterol is optimal.

Congratulations! Your total cholesterol level is in the Desirable range, and your level of "bad" LDL cholesterol is near optimal.

Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is borderline high. If your LDL goes higher, your total cholesterol level could become Borderline High. Consider reducing the amount of foods you eat with saturated fats and increasing physical activity. If you get more exercise, your level of "good" HDL cholesterol may increase, which could also help to keep your levels of LDL and total cholesterol in check.

Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is High. This may mean that your level of high-density lipoprotein (HDL), or "good" cholesterol, is too low. It is best to have a high level of "good" HDL and a low level of "bad" LDL. The HDL helps keep your LDL level in check. Ask your doctor for your HDL level. If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level.

Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is Very High. This may mean that your level of high-density lipoprotein (HDL), or "good" cholesterol, is too low. It is best to have a high level of "good" HDL and a low level of "bad" LDL because the HDL helps keep your LDL level in check. Ask your doctor for your HDL level. If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level.

Your total cholesterol level is Borderline High, but fortunately your level of "bad" LDL cholesterol is optimal. This could mean you have a high level of high-density lipoprotein, or "good" HDL cholesterol, which protects against heart disease. Or you could have other non-measured increases in LDL-like particles that can increase heart disease. Your LDL level also could be optimal if you are taking a statin medication. Please check with your doctor to get your complete lipid profile and see if you may need additional treatment. In the meantime, find more information on WebMD's Cholesterol Health Center.
